Description

Technical Field

[0001] This utility model relates to the field of railway shunting technology, specifically to a centralized control system for microcomputer interlocking of key areas of multiple turnouts in railway shunting. Background Technology

[0002] Traditional non-centralized, non-interlocking turnout shunting areas typically use a large number of hand-operated spring turnouts. Hand-operated spring turnouts are relatively inexpensive and simple in structure, but they are less safe, less efficient, require a large number of workers, and are physically demanding.

[0003] The existing technology in the centralized control system for microcomputer interlocking of key areas of multiple turnouts in railway shunting, application number CN201420859649.4, can solve the above problems. The centralized control system for microcomputer interlocking mainly includes a control panel, a controller, an electric switch machine, and track circuits. The control panel and the electric switch machine are both connected to the controller. The power output end of the electric switch machine is located at the turnout tip. The electric switch machine has the function of controlling and automatically locking the turnout connection between the turnout tip rail and the turnout stock rail.

[0004] Because electric switch machines need to reciprocate and control the movement of turnout switch points and control multiple sets of turnouts, the internal gears and racks of the electric switch machine are prone to wear, which in turn affects the operation of the electric switch machine. Therefore, regular lubrication and maintenance of the electric switch machine are required to reduce wear. The existing maintenance method is generally to open the cover of the electric switch machine and manually add lubricant to the gears and racks, which is relatively troublesome and inconvenient to maintain, affecting the normal operation of the electric switch machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a centralized control system for microcomputer interlocking of key areas of multiple turnouts in railway shunting. This system solves the problem that the maintenance of internal gears and racks in some electric switch machines is cumbersome and inconvenient, as it involves manually opening the switch machine housing cover and adding lubricant.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centralized control system for microcomputer interlocking of key areas of multiple turnouts in railway shunting includes a switch machine unit and a turnout unit, wherein the turnout unit is located on one side of the switch machine unit, and the switch machine unit includes:

[0007] A drive component for switching multiple sets of turnouts;

[0008] A lubrication assembly is disposed above the drive assembly and is used to synchronously lubricate the drive assembly.

[0009] Preferably, the switch machine unit further includes a housing, on which a housing cover is provided, and the housing cover is movably connected to the housing.

[0010] Preferably, the housing contains an equipment box, which contains a motor and a reducer, used to drive the turnout to move.

[0011] Preferably, the driving component includes:

[0012] The gear is fixedly connected to the output end of the motor;

[0013] A rack, wherein the rack is disposed below the gear and the rack and the gear are meshed together;

[0014] An actuating lever, which is fixedly connected to one end of a rack and connected to a turnout unit;

[0015] A guide rod is fixedly connected to the other end of the rack.

[0016] Preferably, the rack is slidably connected within the housing.

[0017] Preferably, the lubrication assembly includes:

[0018] A liquid storage bottle, wherein the liquid storage bottle is disposed on the outside of the housing;

[0019] A connecting seat, which is fixedly connected to the inside of the housing;

[0020] A cam, which is rotatably connected to a connecting seat;

[0021] A hose is positioned above a cam, and the hose moves against the cam. The cam is used to control the flow and shut-off of liquid within the hose.

[0022] A fixing plate is disposed above the hose and is fixedly connected to the inner wall of the box.

[0023] Preferably, the cam is disposed on one side of the gear and is fixedly connected to the output end of the motor.

[0024] Preferably, one end of the hose is connected to the liquid storage bottle, and the hose is installed at the bottom of the fixing plate.

[0025] This utility model discloses a centralized control system for microcomputer interlocking in key areas of multiple turnouts in railway shunting, which has the following beneficial effects:

[0026] This railway shunting multi-set turnout key area microcomputer interlocking centralized control system is equipped with a lubrication component. A lubricant reservoir is installed on the outside of the electric switch machine, connected to a hose. A cam moves against the hose, ensuring that when the electric switch machine is not running, the cam and hose remain in contact, preventing lubricant dripping. When the electric switch machine is running, the motor rotates the cam, causing it to separate from the hose and open, allowing lubricant to drip through the hose onto the gears and rack. This ensures synchronous lubrication of the gears and rack during operation, reducing wear and extending the service life of the electric switch machine. Furthermore, it eliminates the need for manual opening and maintenance, making maintenance more convenient. Attached Figure Description

[0035] This utility model discloses a centralized control system for microcomputer interlocking of key areas of multiple turnouts in railway shunting.

[0036] Example 1

[0037] According to the appendix Figure 1-5 As shown, it includes a switch machine unit 1 and a turnout unit 2. The turnout unit 2 is located on one side of the switch machine unit 1. The switch machine unit 1 includes:

[0038] Drive component 12, drive component 12 is used for switching multiple sets of turnouts;

[0041] Furthermore, an equipment box 112 is provided inside the housing 11, and a motor and a reducer are provided inside the equipment box 112. The motor and reducer are used to drive the switch point rail to move.

[0042] Furthermore, the drive component 12 includes:

[0043] Gear 121 is fixedly connected to the output end of the motor.

[0044] A rack 122 is disposed below a gear 121, and the rack 122 and the gear 121 are meshed together.

[0045] Actuating rod 123 is fixedly connected to one end of rack 122 and connected to turnout unit 2;

[0046] Guide rod 124 is fixedly connected to the other end of rack 122.

[0047] Furthermore, the rack 122 is slidably connected inside the housing 11.

[0048] Furthermore, according to the prior art of the centralized control system for microcomputer interlocking of key areas of multiple turnouts in railway shunting (application number CN201420859649.4), the switch machine unit 1 is connected to both the control panel and the controller. The power output end of the switch machine unit 1 is located on the turnout switch rail. The switch machine unit 1 has the functions of turnout tight contact control, i.e., tight contact control between the turnout switch rail and the turnout main rail, and automatic locking. The track circuit consists of rails, track circuit insulation joints, and rail connections. The rails of the track circuit are located in the track circuit insulation joints at the beginning and end of the turnout in the key area. When a shunting train enters the track circuit insulation joint, a current loop is formed between the two rails through the train's wheels, axles, and other conductive components. When the train leaves the track circuit insulation joint ahead, the current loop is broken, and the control area is cleared.

[0049] Example 2

[0050] According to the appendix Figure 1-5 As shown, it includes a switch machine unit 1 and a turnout unit 2. The turnout unit 2 is located on one side of the switch machine unit 1. The switch machine unit 1 includes:

[0051] Drive component 12, drive component 12 is used for switching multiple sets of turnouts;

[0052] Lubrication component 13 is disposed above drive component 12 and is used to synchronously lubricate drive component 12.

[0053] Furthermore, the lubrication assembly 13 includes:

[0054] A storage bottle 131 is located on the outside of the housing 11. The storage bottle 131 contains lubricating fluid, and a pumping mechanism is provided at the storage bottle 131. The pumping mechanism enables the lubricating fluid to enter the hose 134 from the storage bottle 131.

[0055] Connecting seat 132 is fixedly connected to the inside of housing 11;

[0056] Cam 133 is rotatably connected to connecting seat 132;

[0057] Hose 134 is positioned above cam 133 and moves against cam 133. Cam 133 is used to control the flow and shut-off of liquid in hose 134.

[0058] A fixing plate 135 is disposed above the hose 134. The fixing plate 135 is fixedly connected to the inner wall of the housing 11. The fixing plate 135 is used to install the hose 134 to prevent the position of the hose 134 from shifting during the rotation and compression process of the cam 133.

[0060] Furthermore, one end of the hose 134 is connected to the storage bottle 131, and the hose 134 is installed at the bottom of the fixed plate 135. By setting the storage bottle 131 containing lubricating fluid on the outside of the electric switch machine, and connecting the storage bottle 131 to the hose 134, and by the cam 133 moving against the hose 134, the cam 133 and the hose 134 are tightly pressed together when the electric switch machine is not running, so that the lubricating fluid will not drip out. When the electric switch machine is running, the motor rotates and drives the cam 133 to rotate, so that the cam 133 and the hose 134 separate, so that the hose 134 opens, and the lubricating fluid can drip through the hose 134 to the gear 121 and the rack 122, so that the gear 121 and the rack 122 can be lubricated synchronously during the movement, thereby reducing the wear of the gear 121 and the rack 122. This not only extends the service life of the electric switch machine, but also avoids the operation of manual opening and maintenance, making maintenance more convenient.
